Pi Is More Than a CLI: A Map of Its Core Libraries for Building Your Own Agent
solyarisoftware · x · 2026-10-18
@xiaomovps breaks down Pi's core library monorepo, showing how to pick pieces for your own agent stack:
- pi-ai: unified multi-provider LLM API (OpenAI/Anthropic/Google) with auth, token & cost tracking, mid-session model switching
- pi-agent-core: stateful agent runtime for tool calls and event streams
- pi-tui: terminal UI with differential rendering, no flicker
- pi-durable: persists conversation/tool state before executing, resumable after crashes (experimental)
- pi-mcp: standalone MCP client supporting stdio and Streamable HTTP
For just coding with Pi, pi-coding-agent bundles everything except pi-durable — which is why several vendors build on Pi.
